Heterobranchia mollusca from Ghana: The traditionally called dendronotacea and arminacea

Abstract

Seven species of Dendronotacea and three of Arminacea collected in Ghana between 1963 and 1973 are described. Three are new species: Marionia ghanensis, Kabeiro atlantica and Janolus kinoi, while two more require further material before they can be definitively identified: Doto species A and Armina species A. Hancockia uncinata, Scyllaea pelagica, Tethys fimbria, Tritonia manicata and Janolus hyalinus occur widely in the north-east Atlantic. Specimens of five species were found on Sargassum so these could easily drift considerable distances across the ocean, which could account for their wide geographical occurrence.
